I think a common trait that successful investors share is that they all tend to be voracious readers. They consume information at an alarming pace and every morsel of data becomes part of their framework for evaluating investments.
That said, I'd like to share some of my favorite books. I'll separate them by topic and try to update them regularly.
Value Investing: From Graham to Buffett and Beyond by Bruce Greenwald
Common Stocks and Uncommon Profits and Other Writings by Philip A. Fisher
Valuation: Measuring and Managing the Value of Companies by Mckinsey & Company
Distressed Investing by Martin J. Whitman
The Dhandho Investor by Mohnish Pabrai
Empire of Wealth by John Steele Gordon
The Big Short by Michael Lewis
The Greatest Trade Ever by Gregory Zuckerman
The General Theory of Employment, Interest, and Money by John Maynard Keynes
Peddling Prosperity by Paul Krugman (published in 1995 before he became a political shill)
Influence: The Psychology of Persuasion by Robert B. Cialdini
Extraordinary Popular Delusions and the Madness of Crowds by Charles Mackay
